PLHOW.

SPECIFICATION forming part of Letters Patent No. 698,023, dated April 22, 1902. Application tiled October 30, 1901. Serial No. 80.552. (No model.)

To all whom it may concern:

Be it known that I, AXEL KAP, of Eagle Bend, county of Todd, and State of Minnesota, have invented certain new and useful Improvements in Plows; and I do hereby declare the following is a full and clear description.

My invention relates to plows.

The objects of myinvention are to provide a gang-plow with means whereby each plow may have a rising movement independent of the other or others for the purpose of passing over and avoiding obstructions, such as stones and the like. I prefer to provide the gang-plow with wheels and in connection therewith the mechanism for lifting the plows out of the ground upon the wheels when the plows are not being used, as in driving to and from the field or in turning around or the like.

With these objects in view my invention consists in the followingr construction and combination of parts, the details of which will first be fully set forth and described, and the novel features thereinafter pointed out and claimed.

Figure 1 represents a perspective view of a gang-plow to which I have applied my improvements. Fig. 2 represents a side elevation of the same, and Fig. 3 represents a similar view showing the plow-beams raised.

1 is an axle carrying a set of wheels 2.

3 represents a rectangular vertical frame carrying two sets of vertical standards 4,. all four of which are secured to the axle 1. The inner wheel 2 is journaled between these sets of standards and the plow-beams, which latter are carried between the pairs of standards on each side of the wheel.

5 is a shaft rigid with the frame 3, to which the front ends or clevises of the plow-beams are secured. Brace -Ibars 6 projecting forwardly from the standards 4 serve to maintain the position of the shaft 5. The standards 4 serve as guides for the plow-beams 7. The draft tongue or pole 8 is carried by a frame 9, secured to the shaft 5.

10 and 11 are braces connecting theouter end of the axle l with the frame 3 and the frame 9.

The frame is provided with a cross-piece 12, and upon this cross-piece is pivoted a lever 13, the front end of which is provided with a vertical link-bar 14, connected with the shaft to which the plows are attached. The rear end of the lever 13 is provided with a handle 15,' carrying a locking device by means of which the lever may be raised and lowered for the purpose ot' raising and lowering the plowbeams. For this purpose one of the plow-v beams 7 is provided with a segmental notched upwardly-proj ecting bar 16,by means of which the lever may be locked at any suitabledegree of inclination. pressed, so that the lock drops into the notch 17, the inner plow-beam is raised sufliciently high to take that plow out of the ground, and through its connection with the gang plow coupling 18 the other plow is also lifted clear of the soil.

The gang plow coupling 18 comprises a rigid frame attachment 19, securely fastened to the inner plow beam 7. It is provided When lthe lever is dewith an upwardly-extending frame portionV l .20, carrying a laterally projecting vertical bearing 2l. rI he outer plow-beam '7 is provided with a rigid coupling 22, having a laterallyprojecting vertical shaft 23, which passes through and has a vertical play within the projecting bearing 2l upon the other plow. It will be seen that each plow has an independently rising-and-falling motion with respect to the other plow upon the vertical bearings 21 and 23, which permits either plow upon striking a stone or other obstruction to ride over the same without affecting the other plow or taking it from the soil. When the lever 13 is depressed for the purpose of taking the plow out of the ground, the inner plowtirst rises until its bearing 21 reaches the upper limit of the bearing 23 of the outer plow, and upon further depressing the lever 13 the outer plow will also be raised clear of the ground.

It will be noticed in my construction that the plows are perfectly guided by the frame 3 and that the inner wheel of the plow runs upon and parallel also within the frame 3. The result of this construction is a very compact plow in which all the wheels of the plow run upon the stubble or land side at all times except when iinishing a field. This is a very important arrangement for the reason that none of the IOS wheels are in the furrow or plowed ground, Where the traction is greater and requires more draft from the team.

It will be understood .that While I have shown exemplifying means for carrying out the spirit of my invention yet my invention is not limited to the specific construction set forth and described. On the contrary, my invention contemplates all departures or changes from the specific construction herein set forth which are Within the scope ol my claims.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a plow, the combination of wheels, an axle, a frame carried by the axle, one of the wheels mounted within the frame, plows mounted upon both sides of the wheel within the frame, a gang-coupling located in rear of the axle connecting the plow-gangs to permit independent vertical movement thereof and a loek'lever for elevating the plows.

2. In a plow, the combination of plowbeams, a frame, an axle and wheels mounted in the frame, whereby the inner wheel runs between the plow-beams, and a gang-coupling for the plow-beams located in rear of the axle permitting independent vertical movement of each of the plows.

3. In a wheel-plow, the combination of two plows, a coupling directly connecting the two beams of the plow-gangs, said coupling comprising vertical bearings which permit the independent rise and fall of each plow-beam.

4. A gang-plow coupling comprising two members, each provided with clips for securing the plow-beam thereto and each provided with inner projecting members having vertical sliding bearings, whereby one member of the coupling may have a vertical movement with respect to the other.

In testimony whereof I have ai'lixed my signature in the presence of two witnesses.
